  • Made of high quality plastic, aquarium transparent, automatic accurate reading brine hydrometer.
  • Accurate, durable and easy to read salt and specific gravity of your marine aquarium, small and waterproof. If the specific gravity is between 1.000-1.019, it indicates that the specific gravity is low.
  • if the specific gravity is between 1.020-1.023, it indicates that the specific gravity is normal.
  • if the specific gravity is between 1.024-1.030, it indicates that the specific gravity is high.
  • The external range of the scale indicates salinity (PPT), and the internal range of the scale indicates gravity. And clearly mark the safe area. Application range: 0-40 degrees (1.000-1.030). If the salinity PPT is between 32-40, it indicates that the salinity is high.
  • if the salinity PPT is between 27-31, it indicates that the salinity is normal.
  • if the salinity PPT is between 0-26, it indicates that the salinity hydrometer is low.
  • Wide range of applications: Suitable for salt water and sea water fish tanks. Perfect for testing salinity and specific gravity of saltwater and seawater tanks, including solubility and specific gravity scales. Suitable for fresh water and sea water.
  • Easy to read swing arm pointer and ultra wide stable base can provide accurate test results.

RCYAGO Dissolved Oxygen Meter with Electrode Filling Fluid

  • Dissolved oxygen meter is a precision instrument for measuring dissolved oxygen and temperature. The dissolved oxygen probe is a thin film with a polarographic sensor and a thermistor for temperature measurement and temperature compensation. The permeable membrane separates the measured solution from the sensing electrode but allows oxygen to pass through the membrane to react, and the concentration can be measured..
  • Dissolved oxygen refers to the concentration of molecular oxygen dissolved in water, generally expressed in mg/L (ppm) and saturation percentage (%), which is the percentage of dissolved oxygen in 1L of water. The oxygen concentration of our dissolved oxygen meter is 0.0-40.0mg/L, most of the range of dissolved oxygen meters on the market is 0.0-20mg/L. When measuring and calibrating, needn't open the protective cover of the electrode, just put the electrode in the solution for measurement..
  • Detachable probe, easy to replace, equipped with 6 probe protective covers and anaerobic water calibration powder. The film inside the protective cover cannot be taken apart. After using it for a period of time, the test value is inaccurate and the calibration is still inaccurate, and the membrane sleeve needs to be replaced..
